CIGARETTE momma Homer At Mason, 'Ghicago; 111*. Application July 2;, 194asenatm meteo invention appertains tocigar and cigarette li hters.

Ans important obiectot my invention is to provide a cigarette lighter made of. transparent material; such as plastialucite, or glass, iflso desired; however; Lucite is; preferable as material, so as .to show clearly the. complete mechanism therein,v and thus act asla great aid to the avera e layman: unfamiliar withrmechanical' structure, who would bet-apt tense-such a: device, so as toxindicatevery clearly means for adjustingv the device, or filling or dismantling, or assembling UhBr'S ame :whemadiustments or repairs are needed.

Another object of myuinventionisto provide a lighter of; the atone-mentionedcharacter, which hasuan auxiliary well for retaining. therein an extra spare supply of volatile. lighter fluid, the said well-Vbeingvprorided with valve means communicating; withrthe. wellof. the lighter, so as .to

permit filling the mainwelltof' the lighter from acting as a; seal t-herecver, preventing the evaporation of the lighter fluid, which is highly volatile in character ,A further objectlof my invention is tonprovid'e a cap cooperating with spring detent means for retaining the said capin open, andlclosed p'osi 'tions under resilient pressure, formihea hermeticalseal whentin closed positionover the exposed portion of vthe ltghter wick.

A further objectof .myinvention is to provide an article of the atom-mentioned" character,

which is practicallini construction, efficient f or the purposes and uses. for which it islto. be applied,

andv ofi such simple elementalldesign as to warrant economical manufacture thereof in quantity production.

Other featuresaand objects inherent in my invention, will become apparent" from an examination: of the: accompanying drawings, having numerological reference to the ensuing description, wherein like numeralslarev used to designate like parts, and' in which;

Fig. 1 is a front view of my lighter invention depicting: the capnin openlposition ready-'forcuse.

Referring to the various views, my invention is generally designated 5, and consists of a body element 6', made of transparent material, and a .cap elementlll also madeof transparent material, thesaid cap having an enlarged cap portion 23 and-a reduced-hody portion which is slidablyand finictionallyconfined between the slotted confinesz'z formedbetweenthe.ledges [land 2] of thebody 6. Thecap is pivot'ably secured by cirtueioithe pivot axle. 1.8; which is a screw havin a. threaded. portion. I 9 firmly secured into the ledge 12. The-ledge l2v alsohasa bore" therein, in which is confinedi-aspring. element I B; urging the flint 15. against. the.- scraper or: spark wheel ll4,twhichvinturn is pivoted by, means'of the axle screw l3.

The spring, element .lfii'sl confined in its compressedi state within the bore by. virtue of" the knurledlhead screw lT secured'to the ledge lfl'at the terminus of the liore therein To replace flint, .thelscrew I T, ,an'dthe spring? [6, are removed and a new piece of'flint I5 is inserted; thelspring and screw being replaced to hold" the .fii'nt under .resilifentlpressure. against the teeth of the spark wheel l' l'.

Adjacent the spark wheel; and'adaptedto cap"- ture the sparks created thereby, when" the same is rotatedagainsttheflint I5; is the wick bushing all, which. holds a wick vIll, itsterminus being in the. cottonhatting. or packingim'aterial' 9, within the mm or lighter fiuid chamber 8; th sa being tightly sealedb'y means of the screw plug 38, which is removed; whenin'e'w packing or wicking is to he ii sertedi into the? tubular holder I1".

A' spare fuel" reservoir 1' is provided in my lighter Whlchis fil1'd,'.With" volatilelighter fluid 2?! and held'in sealed" closure by means of" the screwiplug, 3.11 A1featureflofmyinvention is the valve element having a head 28; azthreaded'portion ,3. I engagingja mating 'fema'le threaded portion in the kiody filandhavin'ga' reduced exten sion '32; The. said'ivalire' extension 32 is provided Withla, .chamfered portion 4 l -a;dapt'edto"be lodged in sealingirelationship' with: the valve seat 35 which is-ofcounter-sunk formation" with refer- .ence to the bore 3'61 It is'to' be noted.that the endiof the valve extension" 3Zi sT axially drilled asindioated atfand crossadfilledas-at- 34, so that when the va1i/e12'8"is' in" closed position (see Fig, 3)" the intersecting orcross bores 3'4 are outside of the prpvinceoftlie bore" 1; whereas the ,chamfred portion is seated an'd'lodged against the eounter sunkportion'; thus the-liquid within the reservoir: Tha'sno outlet or'fi'owing connection to the reservoirrs'; whereas whenthe' valve headlZSis.loosenedione'ormore turns? as may be the reservoir 8; thus small quantities of the spare fuel may be passed from the storage chamber I, 01 reservoir 1, to the chamber 8, which maintains the wick moist, through capillary action and proper conditions, so that the sparks will ignite the liquid at the free portion thereof, whenever the spark wheel [4 is rotated, or actuated.

It is to be noted that there is a space 29 (see Fig. 3) between the bottom portion of the knurled head 28 and the side, or face 30, of the lighter 6, so as to make certain that the chamfered portion M will be firmly, and hermetically seated against the counter-sunk portion, or seat 35, assuring no communication between reservoirs l and 2 when the valve is closed, or in inoperative psiion,

The cap portion 23 is provided with a bored out housing portion 24, which fits over the exposed portion of the wick l0, when the lighter is closed, and is retained in sealed relationship therewith by virtue of the spring 26 confined in the longitudinal bore in the body 6, and having a hemispherically tipped pin 25 fitted thereinto, in order to engage either one of the indentations 39 or 40, depending on whether the lighter is open or closed. When in open position, the notch 40 is engaged by the top of the pin 25, as shown in Fig. 1, and when closed, the notch 39 is engaged by the tip of the pin 25.

It will be obvious that various changes in the lighter hereinabove described, and in the structural details of the several parts thereof, may be made without departing from the spirit and scope of the invention, as defined and limited in the subjoined claims.

Having thus described and revealed my invention, what I claim as novel and desire to secure by Letters Patent is:
